In electronicstamil choke is an inductor used to block higher-frequency alternating choking AC in an electrical circuitwhile passing lower-frequency or direct current DC.
A choke usually consists of a coil of insulated wire often wound on a magnetic corealthough some consist of a doughnut-shaped "bead" of ferrite material strung on a wire. The tamil impedance increases with frequency.
Its low electrical resistance passes both Meaning and DC with little power loss, but its reactance meaning the amount of AC passed. The name comes from blocking—"choking"—high frequencies while passing low frequencies. It is a functional name; the name "choke" is used meaning an inductor is used for blocking or decoupling higher frequencies, but is simply called an "inductor" if used in electronic filters or tuned circuits.
Inductors designed for use as chokes are usually distinguished by not having the low-loss construction high Q factor required in inductors used in tuned circuits and tamil girls applications.
Audio frequency chokes AFC usually have ferromagnetic cores to increase their inductance. They are often constructed similarly to transformers, with choking iron cores and an air gap. The iron core helps to improve inductance. A rectifier circuit designed for a choke-output filter may produce too much DC output voltage and subject the rectifier and filter capacitors to excessive in-rush and ripple currents if the inductor is removed.
